5. Convert the following grammar into Chomsky normal form. Show all your steps. S ® abAB A ® bAB|I| B ® Baa|A||

Perform left recursive omission in the following grammar:

Use the CYK algorithm to determine whether the strings abb, bbb, aabba andabbbb are in the language generated byS → AB,A → BB|a,B → AB|b.

14. Write a BNF grammar that describes an arbitrarily long string of the characters a, b, and c. The string can contain any number of occurrences of these three letters (including none) in any order. The strings "empty", a, accaa, abcabccba, and bbbbb are all valid members of this language.

I don't really know where to start.

Consider the following grammar: → a b > b | b b Which of the following sentences are in the language generated by this grammar? a. babb b. bbbabb c. bbaaaaabc d. aaaaaa

Hello, I'm struggling to understand this problem and its elements. Would you mind providing a comprehensive solution with detailed explanations and steps? It would greatly aid my comprehension if you could break it down into clear, labeled sections. Your assistance is sincerely appreciated.

13-Write a grammar for the language consisting of strings that have n copies of the letter a followed by the same number of copies of the letter b and the the same number of copies of the letter c, where n >0. For example, the strings abc, aaaabbbbcccc, and aaaaaaaabbbbbbbbcccccccc are in the language but a, abbc, bac, and aaabbbcc are not

(b) Explain how Java and Python avoid this ambiguity, and suggest a third way to avoid theambiguity.

Computer Science "Production Rule for Context-free Grammars" 7. What is ambiguity with respect to parsing a string w for membership in a language L generated by a context-free grammar G? Why does it master? Can it be mitigated? 8. Chomsky Normal Form: Most useful grammars can be translated into a normal form making answers to questions about the language more transparent.
